A backrest arrangement for installation in a motor vehicle for transporting wheelchair users, and a motor vehicle including the backrest arrangement. The backrest arrangement includes a fixing device that attaches the backrest arrangement to the roof of the motor vehicle. A backrest is mounted to the fixing device and is configured to support a wheelchair user. The backrest is rotatably mounted to the fixing device by a telescoping bar. The backrest may thereby be moved between a stowage position and a substantially extended operative position by rotating the backrest down from the stowage position and extending the telescoping bar. While in the stowage position, the backrest may be disposed completely in the roof region of the motor vehicle so that the backrest arrangement does not take up space in the passenger region.
